Which statement about the relation is true?

• The relation is not a function of x because all functions are linear

• The relation is a function of x because values of x increase toward infinity

• The relation is a function of x because each value of y corresponds to one value of x

• The relation is not a function of x because more than one value of y may correspond to the same value of x

What is the domain of this relation? {(2, 140), (5, 350), (14, 980)}

• {2, 5, 14}

• {140, 350, 980}

• {all whole numbers from 2 to 14}

• {all whole numbers from 140 to 980}
